<h3 id="spring-security"><a href="#spring-security" class="headerlink" title="spring security"></a>spring security</h3><p><strong>1. 使用目的</strong>：验证，授权，攻击防护。<br><br><strong>2. 原理</strong>：创建大量的filter和interceptor来进行请求的验证和拦截，以此来达到安全的效果。</p>

<h4 id="这里只记录-springboot-整合-spring-security"><a href="#这里只记录-springboot-整合-spring-security" class="headerlink" title="这里只记录 springboot 整合 spring security"></a>这里只记录 springboot 整合 spring security</h4><p>1. 创建springboot项目，切记是新建Spring Initializr<br>1. 添加依赖</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">&lt;dependency&gt; </span><br><span class="line">    &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;</span><br><span class="line">    &lt;artifactId&gt;spring-boot-starter-security&lt;/artifactId&gt;</span><br><span class="line">&lt;/dependency&gt;</span><br></pre></td></tr></table></figure>
<p>3. 仅需添加依赖即可启动，启动后通过游览器进入8080端口，会自动跳转到Security内置的login页面</p>
<ul>
<li>用户名默认为user </li>
<li>密码：控制台中有自动生成</li>
</ul>
<p>4. 自定义登录页面</p>
<ul>
<li>我们通过Thymeleaf来实现，先创建一个登录页面<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br></pre></td><td class="code"><pre><span class="line">&lt;!DOCTYPE html&gt; </span><br><span class="line">&lt;html lang=&quot;en&quot; xmlns:th=&quot;http://www.thymeleaf.org&quot;&gt; </span><br><span class="line">&lt;head&gt;</span><br><span class="line">    &lt;meta charset=&quot;UTF-8&quot;&gt; </span><br><span class="line">    &lt;title&gt;Title&lt;/title&gt; </span><br><span class="line">&lt;/head&gt; </span><br><span class="line">&lt;body&gt;</span><br><span class="line">    &lt;h1&gt;登录管理&lt;/h1&gt; </span><br><span class="line">    &lt;form th:action=&quot;@&#123;/login&#125;&quot; method=&quot;post&quot;&gt; </span><br><span class="line">        账号:&lt;input type=&quot;text&quot; name=&quot;username&quot;&gt;&lt;br&gt; </span><br><span class="line">        密码:&lt;input type=&quot;password&quot; name=&quot;password&quot;&gt;&lt;br&gt; </span><br><span class="line">        &lt;input type=&quot;submit&quot; value=&quot;登录&quot;&gt;</span><br><span class="line">    &lt;/form&gt; </span><br><span class="line">&lt;/body&gt; </span><br><span class="line">&lt;/html&gt;</span><br></pre></td></tr></table></figure></li>
